Carbon dioxide insufflation during colonoscopy can significantly decrease post‐interventional abdominal discomfort in deeply sedated patients: A prospective, randomized, double‐blinded, controlled trial

Abstract

Compared with air, CO2 insufflation during colonoscopy reduced postcolonoscopy abdominal discomfort and improved patients' satisfaction. It was safe to use CO2 insufflation in deeply sedated colonoscopy.
